How to beautify json with vscode

Beautifying JSON data in VS Code can be achieved by using the Prettier extension to automatically format JSON files so that key-value pairs are arranged neatly and indented clearly. Configure Prettier formatting rules according to your needs, such as indentation size, line breaking method, etc. Use the JSON Schema Validator extension to verify the validity of JSON files to ensure data integrity and consistency.

Make your JSON data pleasing to the eye in VS Code

Processing JSON data is a link that every developer cannot avoid. Whether it is configuration files in front-end development or data interaction in back-end development, JSON is everywhere. A well-formatted and easy-to-read JSON file can significantly improve development efficiency and reduce errors. VS Code, with its powerful expansion capabilities and rich functions, can easily help you beautify JSON data, making your work easier and more enjoyable.

Many developers may simply use a text editor to open a JSON file at the beginning, facing a long list of nested brackets and dense key-value pairs, all of which are big. At this time, the advantages of VS Code are reflected. Its built-in JSON support is already pretty good, it can automatically highlight syntaxes and prompt incorrect JSON syntax, which is much better than a simple text editor. But to truly achieve "beautification", some expansions are needed.

I personally recommend Prettier this extension. After installation, it will automatically format your JSON file, arrange the key-value pairs neatly, indent them clearly, and make the entire file clear at a glance. You can configure Prettier formatting rules according to your preferences, such as indentation size, line breaking method, etc. It's like putting on your JSON file a beautiful "clothes" to make it easier for you to understand and modify the contents.

For example, suppose you have a very messy JSON file, like this:

<code class="json">{"name":"JohnDoe","age":30,"address":{"street":"123MainSt","city":"Anytown","zip":"12345"},"skills":["java","python","javascript"],"projects":[{"name":"ProjectA","description":"Aproject"},{"name":"ProjectB","description":"Bproject"}]}</code>

After formatting with Prettier, it becomes:

<code class="json">{ "name": "JohnDoe", "age": 30, "address": { "street": "123MainSt", "city": "Anytown", "zip": "12345" }, "skills": [ "java", "python", "javascript" ], "projects": [ { "name": "ProjectA", "description": "A project" }, { "name": "ProjectB", "description": "B project" } ] }</code>

Is it much more refreshing in an instant? This not only improves readability, but also facilitates code review and debugging. I used to quickly find a hidden error when I was dealing with a large configuration file, and avoid unnecessary trouble because I used Prettier.

Of course, Prettier is not perfect either. Sometimes its formatting rules may not match what you expect and require some custom configuration. Additionally, Prettier may not be able to achieve perfect formatting for some very complex JSON structures. At this time, you may need to manually adjust some details.

In addition to Prettier, VS Code has some other JSON extensions, such as JSON Schema Validator, which can help you verify the validity of JSON files and prompt for parts that do not comply with schema. This is very important to ensure the integrity and consistency of the data. Which extension to choose depends on your specific needs and preferences.

In short, VS Code provides powerful tools to beautify JSON data and effectively improve development efficiency. Making these tools rationally and configuring them according to actual conditions can make you more comfortable when processing JSON data. Remember, a neat code base is the cornerstone of efficient development.
